Summary: This study focuses on the phenomenon of flash floods under arid climate conditions in Gabes, Tunisia, by simulating historical peak flows and recent flood hydrographs using the HEC-HMS model. Calibration of the model based on statistical evaluation criteria resulted in good simulation results, which can be valuable for 1D and 2D hydraulic modeling to simulate water level variations during rainfall events and identify floodable areas.

Summary: With the increasing spatial-temporal variability of rainstorms, it is crucial to understand the impact of this variability on the flash flood discharge process. This study proposes a research framework that utilizes a rainstorm spatial-temporal structure design method and quantitative analysis of flash flood discharge process modeling. By generating rainstorm data with different spatial-temporal variability, the framework simulates the discharge process under different rainstorm scenarios using a hydrodynamic model. The analysis of simulated results improves the accuracy of simulation with the generation of an error correction coefficient. The study's findings highlight how the spatial-temporal variability of rainstorms affects peak discharge, flood volume, and flood peak time.

Summary: This study utilizes seismic data to provide valuable information on flood events in Europe, addressing the deficits of existing gauging networks. Seismic data can deliver key flood metrics and enhance understanding of flood behavior. A combination of low-cost seismometers and existing seismic stations can offer important real-time data for future floods and associated hazards.

Summary: Flash floods are a deadly weather hazard and a significant challenge for governments and societies. They are the most frequent natural disaster in Malaysia, affecting humans, property, and the economy. This study reveals the need for more developed flash flood data analysis in Malaysia, and recommends the creation of a comprehensive Malaysian flash flood dataset for further research and modeling.

Summary: The study identified decreasing trends in flood discharge and sediment yield in the Longchuanjiang watershed from 1965 to 2018. The increase in precipitation extremes in dry-hot valley and decrease in the mountains indicated internal variation in precipitation extremes in the Longchuanjiang watershed. Soil and water conservation measures contributed to the significant reduction of flood discharge and sediment yield under similar extreme precipitation events.

Summary: Compared to perennial streams, there is a lack of studies investigating the impact of large wood on sediment transport and river corridor morphology in ephemeral streams. Both large wood and vegetation effectively confine flow to the main channel, causing it to become wider and deeper. Large wood enhances channel change caused by vegetation, but vegetation has a greater influence on channel morphology due to its larger area within the stream corridor.

Summary: This contribution reviews different models used to identify instream large-wood sources and estimate LW supply to rivers. Two recent GIS-based models, empirical GIS approach (EGA) and fuzzy-logic GIS approach (FGA), were compared in Switzerland. Results showed marked differences between the two models, with FGA estimating larger wood volumes and identifying bank erosion as the predominant process. Despite limitations, these models are useful for hazard assessment and infrastructure design.

Summary: The paper discusses the increasing frequency, extent, and destructiveness of floods in the Sahel region. Analysis reveals that floods occur mainly from late July to August, with human activities and urban planning playing a major role in driving catastrophic floods. It emphasizes the importance of understanding flood impacts, controlling water-borne diseases, and compiling reliable flood information for effective flood risk management.

Summary: Subsurface stormflow is a dominant runoff mechanism in steep humid mountainous areas. This study introduces the bedrock surface topographic index and develops a modified TOPMODEL to improve runoff simulation performance. The modified TOPMODEL performs well in the HBL watershed, especially for peak simulation.

Summary: In this study, the effects of changing CO2 concentration, nitrogen availability, and climate change on hydrologic budget in the Upper Columbia-Priest Rapids watershed were investigated. The results show that increased evapotranspiration in response to climate and CO2 changes contributes significantly to the water balance, while nitrogen availability has a minimal impact. The study highlights the importance of physiological and phenological responses in modulating watershed hydrologic budgets under projected future changes.

Summary: (English Summary:)
Flash floods pose a global threat to humans, and databases are crucial for researching these events. Research has shown that heavy rain-induced floods in Germany occur throughout the country, with a tendency towards fewer events in the northern regions. Seven hot spots have been identified in urbanized and mountainous areas, with more severe injuries and fatalities occurring in events starting in the evening despite most floods happening between noon and late afternoon.

Summary: The study confirms that energy dissipation weighting is the most accurate approach for determining the effective hydraulic conductivity of a binary K grid. The deep learning algorithm UNET can infer K-eff with extremely high accuracy, but it may be less accurate for cases with highly localized flow control structures. The UNET architecture can learn to infer energy dissipation weighting even without direct training, but the representation of weights may not be immediately interpretable by a human user.

Summary: Temperature-based methods are widely used in hydrologic science to infer exchange flux, but they have limitations due to simplifying assumptions. Researchers conducted experiments to investigate the application and limitations of machine learning in inferring exchange flux, finding that machine learning methods need to perform well under perfect conditions before considering real data usage.
